Recently, although the number of cores on a chip multi-processor increases, multi-programming or multi-threaded programming techniques to utilize the whole cores are still insufficient. Therefore, there inevitably exist some idle cores which are not working. This results in a waste of the caches, so-called idle caches which are dedicated to those idle cores. In this research, we propose a methodology to exploit idle caches effectively as victim caches of on-chip memory resource. In simulation
